Shear Strengthening of Skew RC Beams Using Carbon Fiber Reinforced Polymer (CFRP)

The study demonstrates the shear strengthening of skew Reinforced Concrete (RC) beams using CFRP strips.
Skew RC beams are widely practiced in the construction of bridges and flyovers. As there are many cases of
failed bridges and flyovers reported worldwide including in Malaysia, researchers now aggressively find
strategies to repair and retrofit those structures instead of choosing to demolish and reconstruct it is as the costs
become the main constraints. In this study, six simply supported 150mm x 230mm x 2000mm RC beams were
tested to evaluate the effect of CFRP in strengthening skew beams. Two of the beams were treated as control
beams while the other four were wrapped up with CFRP strips. From the static load test, the strengthening of
skew beams using CFRP varied from 21.08% up to 43.47% and from this variation, the effect of CFRP
configuration and skew angle on the strength of the beams were determined.
